我遇到一个问题，app在oppo安卓8.1正常，小米安卓6,安卓8,一加安卓9都正常，但是在红米安卓8.1报android.hardware.Camera.native_takePicture(Native Method)android.hardware.Camera.takePicture(Camera.java:1601) android.hardware.Camera.takePicture(Camera.java:1542) com.xiakesong.xkbj.FaceActivity8$3.onAutoFocus(FaceActivity8.java:653) 而且红米安卓8.1相机看起来像是黑白的，上面还有层阴影，你知道是什么原因吗？
